Please help me fast i will give first answer brainliest!!

see below

Step-by-step explanation:

f(x) = 2x^2 +4x-16

Factor out 2

f(x) = 2 (x^2 +2x) -16

Complete the square inside the parentheses

Take the coefficient of x, divide by 2 and square it

(2/2)^1

f(x) = 2 ( x^2+2x+1   -1 ) -16

Bring the -1 outside the parentheses

f(x) = 2(x^2+2x+1)-2 -16

f(x) = 2(x+1)^2 - 18

This is in vertex form

y = a(x-h)^2 + k  where ( x,k) is the vertex

f(x) = 2(x - -1)^2 - 18

The vertex is (-1,-18)

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
